Hi!
First of all sorry for my English.
I have Acer notebook with core i5 and GT710.
Mojave work perfect, but when I try upgrade or new install Catalina I have error:
*** Panic Report ***
panic(cpu 2 caller 0xffffff7f8aabac31): "virtual bool IOAccelLegacyDisplayMachine::display_mode_did_change(uint32_t): vendor driver returns false"@/BuildRoot/Library/Caches/com.apple.xbs/Sources/IOAcceleratorFamily_kexts/IOAcceleratorFamily-438.2.8/Kext2/IOAccelLegacyDisplayMachine.cpp:267
There are no errors during the installation process.
This is error I see after complete install Catalina, and try boot from Catalina partition (I use config.plist from Mojave).
This is error I see after complete install Catalina, and try boot from Catalina partition (I use config.plist from Mojave).
Any ideas?
